.SH "BESCHREIBUNG"
.PP
The
\fBchsh\fR
command changes the user login shell\&. This determines the name of the user\*(Aqs initial login command\&. A normal user may only change the login shell for her own account; the superuser may change the login shell for any account\&.
.SH "OPTIONEN"
.PP
The options which apply to the
\fBchsh\fR
command are:

Apply changes in the
\fICHROOT_DIR\fR
directory and use the configuration files from the
\fICHROOT_DIR\fR
directory\&. Only absolute paths are supported\&.

.RE
.PP
If the
\fB\-s\fR
option is not selected,
\fBchsh\fR
operates in an interactive fashion, prompting the user with the current login shell\&. Enter the new value to change the shell, or leave the line blank to use the current one\&. The current shell is displayed between a pair of
\fI[ ]\fR
marks\&.
.SH "ANMERKUNGEN"
.PP
The only restriction placed on the login shell is that the command name must be listed in
/etc/shells, unless the invoker is the superuser, and then any value may be added\&. An account with a restricted login shell may not change her login shell\&. For this reason, placing
/bin/rsh
in
/etc/shells
is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell back to its original value\&.
